I have a linux server with mysql installed.There is some data in mysql tables.
Also.I have a .csv file (not from the aforementioned database)
I need to compare the data in the database nad the .csv and print out the difference.
I tried writing a shell script for that but I was unsuccessful.
I need to ask if there's any way I can export the data from mysql tables to .csv file format and use the diff command to see the comparison of the generated file and the file I had initially.
~thanks
